Overview

The LB11820M is a direct PWM drive pre-driver IC that
is appropriate for 3-phase power brushless motors. This IC
can implement motor driver circuits that provide the
desired output capabilities (voltage and current) by the use
of appropriate discrete transistors in the output circuit. The
LB11820M is optimal for driving the large motors used in
air conditioners and on-demand hot water heaters.

Functions and Features

• Three-phase bipolar drive

• Direct PWM drive

• Built-in braking function (Short braking)

• Forward/reverse switching function

• Reverse motion mode protection circuit

• Full complement of protection circuits, include current
limiter, low-voltage protection, and motor constraint
(rotor locking) protection circuits

• Supports control from either a command voltage or a
PWM duty input.

When the OFF mode is selected during reversing at the REVSEL pin, it is necessary to specify the Hall input condition.
With F/R = "L", the condition in which the Hall input is entered in the order from 1 to 6 in the above table is considered the forward rotation and that in the

reverse order is considered reversing.
With F/R = "H", the condition in which the Hall input is entered in the order from 6 to 1 in the above table is considered the forward rotation and that in the

reverse order is considered reversing.

When S/S and PWMIN pins are not used, set the input to the L level voltage.
When REVSEL and BR pins are not used, set the input to the H level voltage or the open condition.
